john :Have you planned your summer holiday yet?
Sam : Yes. I'm leaving next Monday.
John : Where are you going?
Sam : My parents have booked me a week at Campbell's adventure Camp.
John : Adventure camp? What's that?
Sam : It's a teen camp in redwood national park.
John : Wow. You're lucky. I've never been to an adventure camp.
Sam : Would you like to come with me?
John : Thanks, but I'm afraid I can't.
Sam : Why not? Have you made other plans?
John : No, I haven't. I just don't think my parents will let me.
Sam : Let me try to talk to them.
John : Thanks, Sam. You're a true friend.
